| Outline of Final Research Achievements |
Break arcs are generated in a DC resistive circuit. To investigate shortening effect of arc duration by air flow, high flow rate air was blown to the break arcs. The arc duration was shortened to the half compared with the duration when the break arc was only magnetically blown-out. In order to study combination effect of the air flow and the magnetic blow-out, a series of experiments was carried out. The shortening effect of the arc duration by the air flow was insignificant when the magnetic flux density was larger than a certain value.
